WALTER WAIDLICI-I, OF DETROIT, MICHIGAN.

FASTENER FOR BOX-COVERS.

Specification of Letters Patent.

Patented June 8, 1915.

Application filed November 26, 1913. Serial No. 803,273.

To all whom t may concern Be it known that I, WALTER WAIDLIGH, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Fasteners for Box-Covers, of which the following is a specification.

This invention relates primarily to boxes and more particularly to means for fastening a cover to a box.

The object of the invention is to provide a simple and efficient fastening device which prevents the removal of the lid without destruction of the same and thereby prevents the box from being used more than one time.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawing, which forms a part of this application, and in which- Figure 1 is a perspective View of a box employing a hinged lid. Fig. 2 is an inside elevation thereof, the box being shown in section. Fig. 3 is a vertical sectional view taken through the cleat.

. Referring tothe drawing, and more particularly to Figs 1v to 3, 1 represents the body of the box to which is hinged a suitable lid 2. The front side of the box has secured upon the inside thereof a keeper 3 and the lid has hinged thereto a hasp member 4 arranged to lie insidey of the box and pass through the keeper 3, as shown. The lower end of the hasp member is provided with a spear-shaped head 5 toy the lower end of which is secured a spring 'which extends upwardly on both sides of the head and has Copies of this patent may be obtained for ve cents each, by addressing the its terminals inwardly bent, as shown at 7 to overlie the shoulders 8 of the spear head.' The extreme ends of the terminals 7 are upturned, as shown at 9, so as to prevent excessive spreading vof the spring upon upward pressure being exerted upon the lid or cover. When the hasp member is forced through the keeper the sides of the springs will be collapsed until the lower end of the keeper has been passed, at which time they will fly out and engage beneath the keeper sol as to preventV upward movement of the hasp member, as will be readily understood. As all of this mechanisml is located within the box, when the lid is once closed it cannot be opened except by destroying the lid which prevents subsequent use of the box, and thereby prevents refilling and insures to the customer the original contents.

What is claimed is In a box, a body, a lid secured therein, a keeper secured within the body, a hasp member hinged to the lid and arranged to pass through the keeper, a shouldered head on the hasp member, a spring having inwardly bent terminals to rest upon the shoulders of the head and expand beyond the sides of the keeper and means, on the spring for preventing its extreme expansion under pressure.

In testimony whereof I afx my signature in presence of two witnesses.

WALTER WAIDLICH.
